So given how violently the stock market gyrated in the fourth quarter of 2018, the equity landscape should theoretically be teeming with chances to make money.

JPMorgan agrees, and it has pinpointed one specific slice of the market that's offering huge upside: value stocks.

The firm's case is supported by the chart below, which shows that the spread between so-called momentum stocks — a group consisting of the market's proven winners — and their more attractively priced value counterparts is its widest since 2001. This suggests a reversion to the mean could occur.

Of course, no underappreciated area of the market is a sure bet without other elements working in its favor. Downtrodden pockets doomed to stay depressed are called "value traps" for a reason, because they snare overly optimistic investors who blindly assume that a relief rally is due.

That's where JPMorgan comes in. The firm has compiled five reasons value is not, in fact, a trap right now — and why it's set to skyrocket higher at the expense of the momentum cohort. All quotes below attributable to Dubravko Lakos-Bujas, JPMorgan's chief US equity strategist.

(1) There's an extreme valuation spread

That spread, combined with the currently negative correlation between momentum and value, "implies a style reversion."

(2) The dispersion of forward valuations is near a cycle high

"From the peak in dispersion, value outperforms momentum by ~24% and low-volatility by ~11% over the next six months."

(3) Seasonal factors favor value

"Since the 1980s, value exhibits strong seasonal outperformance during January (i.e. 'beginning-of-the-year' effect when investors often sell the expensive winners and bottom fish. On average, value outperforms momentum and low-volatility by ~1.9% and ~1.6%, respectively."

(4) The Fed is moving toward a more dovish stance

"A Fed that is turning more dovish and, importantly, increasing the probability of a US/China trade deal are significant catalysts for value rotation."

(5) The US dollar trend is starting to reverse

"JPMorgan's house view calls for further weakening in 2019. A weakening USD is a risk to momentum. The average correlation of USD versus value is -11%, compared to +19% for USD versus momentum."

How to get involved

For investors looking to get more value-oriented, there are a handful of options. One involves picking specific stocks that look undervalued relative to their peers, which is perhaps the purest form of value investing.

Identifying single companies that are trading at discounts on a forward-earnings basis is one main way to do this — as long as the underlying fundamentals preclude it from being a dreaded value trap.

There's also the avenue of gaining exposure through the exchange-traded-fund market. The biggest value ETF is the $43 billion Vanguard Value ETF (VTV). Through the purchase of shares, an investor can gain exposure to a wide range of value stocks.
